摘要:

背景:在临床治疗过程中,修复体连同黏结材料一同脱落及产生微小渗孔等情况常有发生,因此,探究黏结剂不同使用方式对全酸蚀树脂水门汀与牙本质间黏结性能的影响具有重要的临床意义。
目的:对比黏结剂不同使用方式对全酸蚀树脂水门汀与牙本质间黏结性能的影响。
方法:获取无龋人新鲜拔除的第二磨牙90颗,随机均分为3组,均于常温水冲洗下打磨消除牙冠部位牙釉质,露出牙本质以制备标准黏结面,分别进行不使用黏结剂处理(对照组)、使用经过光照的全酸蚀树脂水门汀处理(实验2组)、使用未经过光照的全酸蚀树脂水门汀处理(实验1组),检测处理后即刻、处理后再经老化处理的微拉伸黏结强度。
结果与结论:处理后即刻,对照组、实验1组、实验2组的微拉伸黏结强度分别为(8.089±3.431),(11.671±2.561),(8.821±2.513) MPa,组间两两比较差异均有显著性意义(P < 0.05);处理后再经老化处理,对照组、实验1组、实验2组的微拉伸黏结强度分别为(1.069±0.421),(7.621±2.061),(4.821±1.513) MPa,组间两两比较差异均有显著性意义(P < 0.05)。表明全酸蚀树脂水门汀与牙本质的结合在黏结剂不同方法的使用中,无论长期还是短期均是使用不光照处理的黏结剂效果最佳。

Abstract:

BACKGROUND: In the clinical course, dental prostheses often fall off together with adhesive materials or produce small bleeding holes; therefore, it is of clinical significance to explore the effect of binders applied via different ways on the bonding performance of total-etch resin cements with the dentin.

OBJECTIVE: To compare the effects of binders used via different ways on the bonding performance of total-etch resin cements with the dentin.
METHODS: Ninety second molars which were freshly extracted from caries-free people were enrolled and randomized into three groups. Enamel crowns were polished and rinsed with water at room temperature to expose the dentin that was used to prepare the bonding surface. Then, these specimens were treated with no binder (control), total-etch resin cements with illumination, and total-etch resin cement with no illumination, respectively. Micro-tensile bond strength was detected immediately after treatment and after ageing treatment.
RESULTS AND CONCLUSION: Immediately after treatment, the micro-tensile bond strength was (8.089±3.431) MPa for the control group, (11.671±2.561) MPa for the group of total-etch resin cements with no illumination, and (8.821±2.513) MPa for the group of total-etch resin cements with illumination, and there were significant differences between groups (P < 0.05). After ageing treatment, the micro-tensile bond strength was changed to (1.069±0.421), (7.621±2.061), (4.821±1.513) MPa in these three groups, respectively, and there were also significant differences between groups (P < 0.05). These findings indicate that the binder treatment with no illumination is an optimal method for the binding between total-etch resin cements and the dentin.
